| The five known species of the African genus Chondrolepis Mabille are extensively described and figured and two new species are added. Keys are given to the males and females separately. Most species are restricted to montane habitats, mainly in East Africa. Based on their phylogeny the geographic history of the species is analyzed. It is concluded that the distribution agrees with the predictions to be derived from the hypotheses that montane forests were very much restricted during the last Glacial Period of the Northern Hemisphere, later on becoming more widespread than at present, and that the contact between the Cameroun highlands and the highlands of East Africa was through species that temporarily lived in the intervening lowland forests and not... |
